Solar energy is one of the most promising renewable energy sources. Research and development of solar cells have gained more value. Recent development in some novel materials has opened possibilities for the production of low-cost and highly efficient solar cells. One such materials system is hybrid organic-inorganic metal halide perovskites.
In recent years, the power conversion efficiency (PCE) of metal halide perovskites (MHP) solar cells have been rapidly improved with PCEs exceeding 25.5% for a single-junction solar cell. Beyond photovoltaic applications, the development of these materials for other applications such as light-emitting diodes (LEDs) photodetectors, and ionizing radiation sensors has been remarkable thanks to their unique optoelectronic properties.
The key remaining challenges blocking widespread application of these materials are their chemical instability and environmental sensitivity. In this talk I will discuss the use of automated laboratory robotics and the use of artificial intelligence/machine learning (AI/ML) to accelerate the discovery and design of compositions and materials processing toward optimized properties including stability of intrinsic materials for solar cells and other applications.

Overview of Advanced Antenna Concepts for 5G Applications (PDH*)
Monday, February 14, 2022
Zoom meeting
Implementation of advanced antenna concepts is essential for the success of the 5G evolution. The use of conventional beamforming networks — like Butler matrix, Blass matrix and the Rotman lenses network in addition to adaptive arrays — is very promising. The utilization of multi-element antennas in addition to deployment of advanced algorithms are the backbone of efficient spatial processing. Various antennas have been developed and can be utilized for beamforming, such as phased arrays and essential components for various MIMO use purposes that could operate in urban or suburban areas. Other antennas with high gain and powerful repeaters have been designed to extend coverage to rural areas as well. In this presentation, we will provide a brief overview of candidates for 5G antennas and discuss the impact of 5G and beyond technology in our society.
Dr. Aly Fathy is a James W. McConnell Professor at the University of Tennessee Knoxville and the Director of the Microwave/5G Labs at UTK. He is an IEEE Life Fellow and a very active researcher. He has been involved in developing UWB radars for SAR and MIMO applications and is focused on developing hardware for time and frequency domains UWB application and microwave systems measurements. Dr. Fathy’s research is recognized worldwide in the area of GPS, nm-waves, reconfigurable RF front ends, power combiners, and UWB radars. Additionally he has pioneered the development of reconfigurable antennas (sponsored by Intel and DAPRA). Moreover, he has developed many microwave enabling technologies (sponsored by ONR, DARPA, NASA and NRL). Professor Fathy’s research background is in SAR radars, 3D imaging, multi-band, reconfigurable, UWB, and reconfigurable multi-band antenna structures.

The Southern Appalachian Science and Engineering Fair (SASEF)
Monday, January 10, 2022
The Southern Appalachian Science & Engineering Fair is the premier science and engineering competition for students in middle and high school for a 23-county service area of East Tennessee. It is the official, affiliated regional fair of the International Science and Engineering Fair and Broadcom MASTERS, the nation’s premier middle school STEM Competition. It is held annually on the University of Tennessee, Knoxville campus during the last week of March or first week of April.
SASEF has promoted teaching “the scientific method in science, engineering, and math” since 1952. In conjunction with the Knoxville News Sentinel and the University of Tennessee, The Technical Society of Knoxville sponsored the first “Southern Appalachian Regional Science Fair.”
On May 2, 1953, The Society gave the first awards dinner, which was attended by one hundred fifty students. It has continued to support the Fair, providing it with judges and, until 1966, underwriting the banquet. After that year TSK decided instead to donate two cash awards and trophies to the senior division winners in engineering or physics.
SASEF is always looking for scientists, engineers and teachers to serve as volunteer judges. This year’s fair will be held (tentatively) March 29-31, 2022. Register online to judge!
